Embodiment 1
[0026] This embodiment provides a method for extracting and verifying terminal authentication information based on a national secret algorithm;
[0027] Such as figure 1 As shown, the terminal authentication information extraction and verification method based on the national secret algorithm includes:
[0028] S1: Obtain a terminal authentication information file; acquire terminal authentication information from the terminal authentication information file;
[0029] S2: sequentially determine whether the serial number in the terminal authentication information is successfully read, determine whether the verification information is successfully read, and determine whether the verification value of the data segment is successfully verified;
[0030] S3: If the above judgment results are all successful, decrypt the data, re-encrypt the data, output the re-encrypted data, and restore the re-encrypted data.
